After market guages

[kneedragger74]

I would like to get aftermarket guages for Yamaha Radian. How do I figure out what the ratio is for my bike?

I assume you are talking about the speedo? Is it mechanically driven? It more than likely is. The way i figured mine out was i removed the speedo cable from the wheel.
Mark the tire at the very bottom, like where it would meet the ground. Either jack the front of the bike up or roll the bike forward one full tire rotation and count the amount of times the speedo drive turns. If it turns 2.5 times then you have a 1:2.5, etc etc.
Hope this helps

I've found most Japanese bikes are the same ratio. I'm running an aftermarket mini-speedo originally run off my XS650 front wheel off a Suzuki GT750 front wheel and it's fine. Cable is even the same.

Thanks for the replys. I am going to order a tach and speedo from DCC, but was trying to figure which ones I needed.
